Vancouver, British Columbia--(Newsfile Corp. - December 8, 2023) - Silver Elephant Mining Corp. (TSX: ELEF) (OTCQX: SILEF) (FSE: 1P2N) ("Silver Elephant" or the "Company") announces from October 17, 2023 to December 2, 2023, the Company  mined a total of 13,072 tonnes of Paca  oxide materials with an average grade of 190.2 g/t silver ("Products") and trucked the Products to Andean Precious Metals Corp. ("Andean"). All Products are excavated from the Paca resources tabulated below.

Pursuant to the sales and purchase agreement and master services agreement both dated September 12, 2023 between Silver Elephant and Andean, Andean will pay Silver Elephant US$1.8 million by January 31, 2024, or when 36,000 tonnes of Products have been delivered to Andean's processing facility.

John Lee, Silver Elephant CEO, comments: "The continued progress and activities at Paca demonstrated team effort and community support. Silver Elephant aims to grow and maintain local employment; in addition to contributing to government royalties in the months and years ahead."

The Paca project hosts a high grade silver resource according to a technical report by Mercator Geological Services, dated effective October 13, 2020 titled "Mineral Resource Estimate Technical Report for the Pulacayo Project, Potosi Department Antonnio Quijarro Province Bolivia" (the "Technical Report"). The mineral resource estimate from the Technical Report is as follows:

Oxide resources are based on a Pit-constrained estimate using a 90 g/t Ag cutoff. Sulfide resources are based on a pit-constrained estimate using a 200 g/t Ag Eq cutoff. Ag Eq  = Silver Equivalent (Recovered) = (Ag g/t*89.2%)+((Pb%*(US$0.95/lb. Pb/14.583 Troy oz./lb./US$17 per Troy oz. Ag)*(10,000*91.9%))+((Zn%*(US$1.16/lb. Zn/14.583 Troy oz./lb./US$17 per Troy oz. Ag)*(10,000*82.9%)). Sulphide zone metal recoveries of 89.2% for Ag, 91.9% for Pb, and 82.9% for Zn were used in the Silver Equivalent (Recovered) equation and reflect metallurgical testing results disclosed previously for the Pulacayo Deposit.Matthew Harrington P. Geo. is the independent Qualified Person for the resource estimate.

The Technical Report was filed on October 26, 2020 and is available under the Company's profile on SEDAR+ at . This news release includes an estimate of mineral resources as disclosed in the Technical Report. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The Company is studying a proposed Phase 2 for Paca sulphide development. The objective is to start mining Paca sulphide materials and truck them to one of several nearby milling plants that will produce lead-silver and zinc concentrates for sale in 2024.

The Company has in parallel, engaged consultants to prepare and apply for the environmental permit to build a sulphide processing plant to produce metal concentrates on site at Pulacayo. The time table to obtain such permit will be provided in early 2024.

About Pulacayo-Paca

The Paca project is part of the Company's Pulacayo project with a total indicated resource of 106.7 million oz silver, 1.4 billion pounds of zinc and 690 million pounds of lead published in the Technical Report and tabulated below. Silver Elephant and its subsidiaries have spent over $35 million on Pulacayo and Paca, which is considered to be an advanced project with over 96,000 meters of drilling, and a historic feasibility study.

Combined Indicated Mineral Resources includes Pulacayo pit-constrained and out-of-pit plus only Paca pit-constrained resources. Oxide resources use a 50 g/t Ag cutoff. Sulfide resources use a 100 g/t Ag Eq cutoff. Ag Eq  = Silver Equivalent (Recovered) = (Ag g/t*89.2%)+((Pb%*(US$0.95/lb. Pb/14.583 Troy
oz./lb./US$17 per Troy oz. Ag)*(10,000*91.9%))+((Zn%*(US$1.16/lb. Zn/14.583 Troy oz./lb./US$17 per
Troy oz. Ag)*(10,000*82.9%)). Sulphide zone metal recoveries of 89.2% for Ag, 91.9% for Pb, and 82.9%
for Zn were used in the Silver Equivalent (Recovered) equation and reflect metallurgical testing results
disclosed previously for the Pulacayo Deposit. Matthew Harrington P. Geo. is the independent Qualified Person for the resource estimate.

A subsidiary of Silver Elephant entered into a Mining Production Contract ("MPC") with Corporación Minera de Bolivia ("COMIBOL"), a branch of the Bolivian Ministry of Mining and Metallurgy on October 3, 2019. The MPC grants the Company's subsidiary an exclusive right to develop and mine at the Pulacayo and Paca concessions for up to 30 years.

The Pulacayo Project is at the center of a major silver mining district in Bolivia and is within 250 km driving distance to the San Cristobal mine, the Cerro Rico mine, Pan American's San Vicente mine, Eloro's Iska Iska project, and New Pacific's Silver Sands project.
